Abstract

With rapid development of soybean industry in recent years in China, the soybean wastewater is doing greater and greater harm to the water environment. Now the SBR (Sequencing Batch Reactor) process has been widely used all over the world, and the SBR process is a biologic treating process of wastewater with simple structure and flexible operation. For example Anoxic/Oxic (A/O) process can be combined flexibly with SBR process. So in this paper in order to study the removal efficiency of soybean wastewater, the A/O SBR combined process was investigated with anoxic stir for 30min and aeration for 3h. The MLSS was controlled at 2500 mg/L-3000 mg/L and sludge retention time (SRT) can be controlled in 12d-16d. The results showed that the concentration of COD, ammonia nitrogen, nitrite, nitrate and phosphate can reach 50mg/L, 5mg/L, 5mg/L, 4.5mg/L and 1mg/L respectively. Thus the A/O SBR process can obtain good effect for soybean wastewater treatment.
